Struct slog_extlog::stats::StatsLoggerBuilder

pub struct StatsLoggerBuilder<T> where
    T: StatisticsLogFormatter,  {
    pub stats: Vec<StatDefinitions>,
    pub stat_formatter: PhantomData<T>,
}

A builder to allow customization of stats config. This gives flexibility when the other methods are insufficient.

Create the builder using new() and chain other methods as required, ending with fuse() to return the StatsConfig.

Example

Creating a config with a custom stats interval and the default formatter.

slog_extlog::define_stats! {
    MY_STATS = {
        SomeStat(Counter, "A test counter", []),
        SomeOtherStat(Counter, "Another test counter", [])
    }
}

let full_stats = vec![MY_STATS];
let logger = slog::Logger::root(slog::Discard, slog::o!());
let stats = StatsLoggerBuilder::<DefaultStatisticsLogFormatter>::default()
    .with_stats(full_stats)
    .fuse(logger);

Fields

stats: Vec<StatDefinitions>

The list of statistics to track. This MUST be created using the define_stats macro.

stat_formatter: PhantomData<T>

An object that handles formatting the individual statistic values into a log.

Implementations

impl<T: StatisticsLogFormatter> StatsLoggerBuilder<T>

pub fn with_stats(self, stats: Vec<StatDefinitions>) -> Self

Set the list of statistics to track.

pub fn fuse(self, logger: Logger) -> StatisticsLogger<T>

Construct the StatisticsLogger - this will start the interval logging if requested.
